Abstract

During physiological studies, it is often required to restrain a small animal for an experiment, as it is typically challenging to perform in vivo imaging or measurements on freely moving individuals. In this article we describe two widely applicable approaches for repeated restraint of small (approx. 0.5-4 cm) decapods and amphipods that are established in our laboratory: immobilization using gentle gluing and suction. Application of both these approaches as well as their advantages and disadvantages are discussed in detail.
